"Oh, Daddy dear, what is it?" she asked, anxiously.

"I—I'll tell you—presently," he replied, chokingly. "I am a little out of breath. I am getting too—too stout. And my throat has bothered me a good deal of late. Would you mind getting me that throat spray and medicine Dr. Rathby left? That always helps me."

"I'll get it," offered Alice, quickly, as her father sank into a chair, and while she searched in the medicine closet for it, there was a dull ache in her heart. More trouble! And there had been so much of it of late. The sun had seemed to break through the clouds, and now it had gone behind again.

And while the girls are thus preparing to minister to their father, I will tell my new readers something of the previous books of this series, and a little about the main characters.

In the initial volume, entitled "The Moving Picture Girls; Or, First Appearances in Photo Dramas," I related how Mr. Hosmer DeVere, a talented actor, suddenly lost his voice, by the return of an old throat affection. He had just been "cast" for an important part in a new play, but had to give it up, as he could not speak distinctly enough to be heard across the footlights.

The DeVere family fortunes were at low ebb, and money was much needed. By accident Russ Dalwood, a moving picture operator, suggested to one of the girls that their father might act for a moving picture film company, as he would not have to use his voice in such employment.

How Mr. DeVere took the engagement, and how Ruth and Alice followed him, as well as their part in helping Russ to save a valuable camera patent—all this you will find set down in the first book.

In the second volume, entitled "The Moving Picture Girls at Oak Farm; Or, Queer Happenings While Taking Rural Plays," the scene was shifted to the country. There you may read of many strange occurrences, as well as funny ones—how Alice fell into the water—but there! I must save my space in this book for the happenings of it. I might add that, incidentally, the girls helped to solve a strange mystery concerning Oak Farm, and solved it in a way that made glad the hearts of Mr. and Mrs. Felix Apgar, the parents of Sandy, and of the heart of Sandy himself.

Mr. Frank Pertell was the manager of the Comet Film Company, with whom Mr. DeVere and his daughters had an engagement, and the entire company, including the DeVeres, spent a whole summer at Oak Farm, in New Jersey, making rural plays.

The company had just returned to New York City, to finish some dramas there, and Mr. Pertell was working on new plans, which were not, as yet, fully developed.
